FANUC ARC Mate 120iD/12L

The ARC Mate 120iD/12L is a six-axis industrial robot built for arc and laser welding and cutting. It carries up to 12 kg at the wrist and reaches 2272 mm, the longest reach in the ARC Mate series, which lets it weld large parts. It runs on the FANUC R-30iB Plus controller and has a hollow wrist.

Study notes

  • The 12L is the long-arm, hollow-wrist version of the ARC Mate 120iD and has the longest reach in the ARC Mate series at 2272 mm.
  • Smooth exterior surfaces are used to limit spatter build-up in welding and cutting cells.
  • Repeatability of ±0.03 mm is stated as based on ISO 9283.
  • Body protection class is IP54 standard with IP55 optional; the wrist and J3 arm are rated IP67.
  • Average power consumption is listed as 1 kW.
  • The robot is programmed offline in FANUC ROBOGUIDE.
  • The datasheet lists allowable J4/J5/J6 moments of 22/22/9.8 N·m with inertias of 0.65/0.65/0.17 kg·m².
  • The datasheet tabulates per-axis motion ranges and maximum speeds, but the extracted table order is ambiguous, so joint values are not recorded here.
